This invention relates to closure constructions for replaceable head metal containers. or economical reasons it is desirable to use metallic containers repeatedly, and'therepreferably with red an effective and safe seal when in Furthermore, such containers are subjected to all kindsof conditions and rough handling. It is necessary, therefore, that they be strongly constructed, especially at the chimes, where heavy impacts are often received.

A characteristic of the closure constructions h but also they present additional faces anc projectionssubject to damage or destruction. This lias'been a serious disadvantage because the container may be thus rendered useless through inability to replace the heads It is among the objects of this invention the head, tightly seals the container without danger of loosening of the head, reinforces the end of the con tainer, can b o" damage, and has no loose connecting or fastening parts. Other objects and advantages will appear hereinafter.

In the accompanying drawings, Fig. '1 is a side elevation of a metal container, partly in cross section, showing the preferred embodiment of the invention; 13" larged fragmentary cross section of a porof the drum; Fig. elevation of the upper end of a drum, partly cut away, showing a tool for attaching and removing the head; and Fi 8 a plan view of the tool shown in Fig.

In accordance with this invention the open eiidLof a metal container is closed by a head aving a side wall telescoping in the e d'of the container. The side wall is continued f he reinforcing ring; I he invention may be described more in detail by reference to the drawings.v

The free edges 6 of bosses 5 are disposed at an angle. to the plane of the container opening, as shown in Fig. 6, to provide cam surfaces for complementary members associated, with the. head for drawing it tightly upon the container and securing it in place. I

he container is provided with a head container in Asis shown in Fig. 2, the head is provided with an upwardly extending side Wall 8 integral with the body-ofthe'head and adapted to telescope within the container opening. t its upper end side wall 8' is bent outwardly to f is then'bent downwardly to form a skirt 9 surrounding ring '3. There formed an annular recess between the'side wall extension and the lip in whichthere is disposed a sealing gasket 10. Theg'asket preferably is pressed into. thereccssisoas to remain in the corner formedbetween'the side wall and itsex'tension whenthe head is 1 removed. This prevents damage to and reinforcing ring encircling said container on loss of the gasket. the under side of said lip, a plurality of At spaced intervals the edge of the skirt bosses struck out from said ring at spaced is shaped to form inwardly extending gripintervals and having their free edges formed N ping lugs 11 shaped as shown in Figs. 3 to act as cam surfaces, means associated and 1.
